A good recipe for Thai milk tea is something anyone who has tasted the drink at a Thai restaurant or street stall eventually wants at home. The vivid amber color, the creamy sweetness, the contrast of bold black tea against cold condensed milk — it is a sensory experience worth recreating in your own kitchen. This guide walks through exactly how to do that, from choosing the right tea to pouring the finished glass.
What Is Thai Milk Tea?
Thai milk tea (sometimes called Thai iced tea) is a cold drink made from a strong brew of black tea — typically a blend with spices such as star anise and tamarind seed — sweetened with sugar and sweetened condensed milk, then poured over ice and finished with evaporated milk or cream on top. The distinctive orange-amber color comes from the tea itself and, in some commercial mixes, from added food coloring. Homemade versions using plain loose-leaf black tea produce a deep reddish-brown color that is just as beautiful.
The drink originated as a café staple across Thailand and has since become popular worldwide. Because it is made from a black-tea base, Thai milk tea contains caffeine — typically in a similar range to a cup of brewed black tea, though this varies by steep time and the amount of tea used.
Classic Thai Milk Tea Recipe
This recipe makes two generous glasses. Adjust quantities proportionally for a larger batch.
Ingredients
- 3 tablespoons loose-leaf black Thai tea (or 3 heaped tea bags)
- 2 cups (480 ml) filtered water, just off the boil (around 95 °C / 200 °F)
- 3 tablespoons sweetened condensed milk, divided
- 2 tablespoons white sugar (adjust to taste)
- 4 tablespoons evaporated milk or half-and-half, divided
- Plenty of ice
Method
- Brew strong. Steep the loose-leaf tea in the hot water for 5 minutes. For a deeper, more robust flavor you can steep for up to 7 minutes. Strain through a fine-mesh strainer into a heatproof jug.
- Sweeten while hot. Stir in the sugar and half the condensed milk while the tea is still warm so they dissolve fully. Taste and adjust sweetness.
- Cool the brew. Let the sweetened tea come to room temperature, then refrigerate for at least 30 minutes. You can speed this up by pouring it over a large bowl of ice, then straining again.
- Assemble. Fill two tall glasses with ice. Pour the chilled tea over the ice, leaving about 2 cm of space at the top.
- Add the cream layer. Spoon or slowly pour the remaining condensed milk and evaporated milk over the back of a spoon so it floats on top of the tea before you stir. This two-tone look is the classic Thai café presentation.
- Serve immediately with a wide straw so your guest can stir the layers together as they drink.

Tips for Getting the Recipe Right
Use quality loose-leaf tea
The single biggest upgrade you can make to this recipe is starting with a well-sourced loose-leaf black tea rather than a dusty tea bag. Loose-leaf tea releases more nuanced flavor into the brew and gives you better control over strength. If you want to explore the full landscape of Thai teas beyond the classic black-tea base, the guide to buying Thai tea online covers what to look for when choosing an authentic blend.
Steep time is everything
Steep too briefly and the drink will taste thin and pale. Steep too long and it can turn bitter. Five to six minutes at around 95 °C is the sweet spot for most black Thai tea blends. For a full breakdown of temperature and timing principles, the temperature and steeping guide on ArtisanThai covers both black and botanical varieties.
Sweetness is personal
Thai café versions are often very sweet by Western standards. Start with less condensed milk than you think you need — you can always stir more in. For a lighter version, substitute evaporated milk for all the dairy and reduce the sugar by a third.
Make a big batch for gatherings
Scale the brew up in a large pot, sweeten it, refrigerate, and you have the base ready for a crowd. Set out glasses of ice, the chilled tea, and small pitchers of evaporated milk and condensed milk so guests can assemble their own.
Going Beyond the Classic: Thai Botanical Variations
Once you are comfortable with the base recipe, it is worth experimenting with the wider world of Thai infusions. Butterfly pea flower, for example, brews into a striking blue-purple liquid that turns pink when you add something acidic like a squeeze of lime — visually dramatic for entertaining. Lemongrass adds a bright citrus note that works beautifully alongside condensed milk. These botanical infusions are naturally caffeine-free, which makes them useful when you want the visual drama and ceremonial feel of a layered iced drink without the caffeine of black tea.
If you are curious about which botanical blends are worth trying, the overview of authentic Thai botanical infusions is a good starting point, and if butterfly pea in particular interests you, the rundown of top butterfly pea flower tea sources can help you find a quality product.

Frequently Asked Questions
Does Thai milk tea have caffeine?
Yes. Thai milk tea is made from a black tea base, so it contains caffeine — typically in a similar range to a standard cup of brewed black tea, around 40–70 mg per serving depending on steep time and how much tea you use. If you want a caffeine-free version of an iced Thai-style drink, botanical infusions such as butterfly pea flower or lemongrass are naturally caffeine-free alternatives.
Can I make Thai milk tea without condensed milk?
Yes. Sweetened condensed milk is traditional but not essential. Common substitutions include coconut milk with a tablespoon of sugar stirred in (which adds a subtle tropical flavor), oat milk creamer with maple syrup, or regular whole milk with simple syrup. The flavor profile will differ, but the method stays the same.
What kind of tea should I use for an authentic result?
Traditionally, Thai iced tea is made from a blend of Ceylon or Assam black tea, sometimes mixed with whole spices. Using a quality loose-leaf black tea gives you a cleaner, more complex flavor than pre-flavored commercial mixes. Single-origin loose-leaf tea sourced directly from Thai growers is the most authentic starting point for a homemade version.
